My girlfriends dad called me and asked me the best way to destroy a drive (dentists office friend of his) and I told him to drill a bunch of holes in it or use one other their guns to shoot it up. They chose the gun route and took no prisoners. I was so proud of their work on the hard drive. Filled with holes and massive dents.

Agree that it doesn't look like a drill because of the paper but I was thinking it looked more like a .22 especially because of the lack of penetration on some of them. I will defer to dimforest​ who probably more about that.

You said it was from a drill but given how the paper has remained "untwisted" and mangled... that actually looks to be 9mm.

You think? That's a 2.5" drive, and those screws are TEENY... I bought the drill thing, because that would be a much smaller caliber than 9mm, or even .22, from the look of it, but you're right about the label looking really 'clean'.

Now that I think about it, a single hit from a shotgun shell with birdshot or smaller size buckshot would make indentations like that...
